RIFLE SET-LOCK AND SAFETY SET-TRIGGER.

Specification of Letters Patent.

Application filed May 8, 1905, Serial No. 259,366.

To all whom it may concern:

Be it known that I, DANIEL BROWN, a citi zen of the United States,residing at Cranston, in the county of Providence and State of RhodeIsland, have invented certain new and useful Improvements in RifleSet-Locks and Safety Set-Triggers, of which the following is aspecification, reference being had therein to the accompanying drawings.

Like letters indicate like parts.

Figure 1 is a central longitudinal section of my improved rifle set-lockand safety settrigger and the adjacent parts of the rifle with myimproved safety set-trigger in operative position. Fig. 2 is the same asFig. 1 with my improved safety set-trigger in its inoperative position.Fig. 3 is a perspective view of the lever of said lock. Fig. 4 is aperspective view of the trigger. Fig. 5 is a perspective view of thesear. Fig. 6 is a top plan view of the interior of said lock, showingthe arrangement of the springs, lever, and sear, with the trigger incross section. Fig. 7 is an enlarged view of the trigger and itsadjacent parts, showing the trigger in its set position. Fig. 8 is thesame, showing the trigger out of its set position.

My invention relates to rifle or gun locks and to the set-triggers ofthe same; and it consists in the novel construction and combination ofthe several parts, as hereinafter described and specifically set forthin the claims.

In the drawings, Arepresents the hammer, which is pivotally mounted inthe lock in the usual manner. The hammer A is actuated by the spring B,the rear end of which is secured to the tang by the screw 0 and theforward end of which engages with pin P of the stirrup Q. The stirrup Qis pivotally secured to the hammer A at g.

The trigger T is pivotally mounted on the pivot t in the usual way. Theinner end of the trigger T has the part D projecting rearwardly at anangle therefrom and in which or upon which is mounted theantifrictionroller 01. The spring E is secured to the tang by the screw6 and has its inner end adapted to engage with the roller d. The sear Sis pivotally mounted on the pivott and is adapted to engage with thehammer A in the wellknown manner. The sear S has its rear end bifurcatedto form arms 8 and s. The lever L is pivotally mounted at one end to thepivot Z, which is secured in the lock or case of the rifle. The lever Lhas the lip or flange f extending from one side thereof and the aperture9 extending therethrough and the stud h, which extends downward throughan aperture in the tang made for that purpose and which is adapted toengage with the trigger guard or handle F.

The forward end of the lever L is arranged to engage with the arm 8 ofthe sear S. The screw H secures the springs I, J, and K and holds themfirmly in their respective positions in the lock. The spring I has theproj ection t. at the end thereof, which projection is adapted to enterthe aperture g of the lever L. The spring J is adapted to engage withthe arm 8 of the sear S, and the spring K is adapted to engage with thetrigger T and has the lateral projection 7c, which engages with the lipf of the lever L.

The curved portion of the forward end of the spring E'is an arc of acircle whose circumference is larger than that of the roller (1 and isslightly hooked at e. The spring E at 11 so engages with the roller dthat when the point of engagement is very slightly above the lineconnecting the axes of the roller d and the trigger T the trigger isheld somewhat rigidly in this position, and when in this position thetrigger is set ready for firing and is displaced by a very slight pull.If the screw N be withdrawn a little farther than it is necessary tohave it in order to hold the trigger in its set position, then the lowerend of the trigger may be pressed a little farther forward, and then thepoint of engagement between the spring E and the roller at will be alittle farther above said axial line, and the force of the spring E willhold the trigger for ward more firmly and a harder pull will be requiredto fire off the rifle. Usually the screw N is so adjusted that when thelower end of the trigger T is pushed forward as far as it can be thetrigger is then in its set position ready for firing.

When the parts are assembled as explained and the hammer cocked, thetrigger T rests somewhat loosely on its pivot t, as it has not been set.By a forward pressure of the finger or thumb against the back side ofthe lower end of the trigger it is set ready for firing, as shown inFigs. 1 and 2. A slight pull on. the trigger releases it from itsbalanced position and the force of the spring E then causes the'roller dand its adjacent parts to have a forward oscillation and the heel O ofthe trigger T comes into sudden and violent contact with the arms 8 ands of the sear S, and the forward end of the sear is thereby knocked offor out of engagement with the hammer A and the spring 15 allowed to act.7

When the trigger is in its set position ready for firing, a slight jaris liable to fire the rifle off when not desired. My improved safetydevice provides against this and is a simple and effective means thatrenders a rifle safer to handle whether the trigger is set or not, andyet it is readily released from operation when not desired.

The forward end of the lever L is held firmly in engagement with the arm8 of the sear S by the spring I, whereby the accidental disengagement ofthe sear S from the hammer A is prevented. The spring K engages with theheel O of the trigger T and holds it against any sudden and violentmovement of the trigger if it should be accidentally actuated by thespring E. When one is ready to fire, by a slight pressure upon the guardor handle F the lever L is raised by means of the stud h. Theprojections 71 and k of the springs I and K, respectively, engage withlever L or its lip f, and are thus lifted as the lever L is raised, sothat the end of the lever is lifted away from the sear S and the springK is lifted away from the trigger T, as shown in Fig. 2. As soon as thepressure is released from the guard or handle F the lever and springsreturn to their poerative position, as seen in Fig. 1.

I claim as a novel and useful invention and desire to secure by LettersPatent 1.
